abnormal rRNA modification abolished 18S rRNA acetylation abolished 18S rRNA acetylation during vegetative growth abolished 18S rRNA acetylation during mitotic cell cycle A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the posttranscriptional addition of acetyl groups to residues in an 18S rRNA molecule is abolished. FYPO:0005016 midori 18S rRNA acetylation abolished abolished 18S rRNA acetylation on C1297 and C1815 abolished 18S rRNA acetylation at C1297 and C1815 At present, the C1297 and C1815 residues are known to be acetylated. abolished 18s rRNA cytidine (1297 and 1815) acetylation 2015-10-28T16:34:06Z
